TO ALL PESRSON TO WHOM THESE PRESENTS SHALL COME:

Beit known that I, LUCIUS J. KNOWLES, of Warren, in. the county of.Worcester, and State of Massochu setts, have made a new and useful invention having reference to Loomsv for Weaving `Ribbons or Tapes; and do hereby declare the same to be fully described in the following specification, and represented in the accompanying drawings, of whichi Figure 1 is a top view of' a loom containing my invention.

Figure 2 is a front elevation.

Figure 3 is a transverse section; and

Figure ll, a longitudinal section of it.

This latter section being taken through the lay, and lengthwise thereof.

In the drawings, A denotes theframe of such a loom, Baits lay, and (lits cranked shaft for` actuating the lay, such shaft being provided with two-bell-cranks, a a, connected with the lay in the ordinary manner by pitmen or connecting rods, hib. The layrack is shown at l), as arranged within a groove, c, made iu the racebeam d of the lay. 'lwoi leather, or other proper straps, e e, are attached to the rack near its two opposite ends. Each et' these straps passes along underneath the rack `a short distance to and partly around one ot' two guide-wheels,ff, arranged in the race-bcam d, in mannerras exhibited in fig. 4. From the' said wheelthe strap descends and passes underneath and against one of' another pair of guide-wheels, q g, arranged in guides, z' z', projecting from the swords L h of the lay, ,The two straps are connected by rods, 7c k, with a link, l, through the middle of which the pin m of a crank, et, is inserted. The said crank projects from the lower end of au inclined shaft, o, suitably supported in bearings, p p, extending from an inclined brace or bar, F, going from the back lower girt to the front upper girt of the loom frame. The cranked shaft is represented as supported in 1 three boxes, r s r, the middle. one, `n.of such bores being upheld by the inclined brace FQ A bevel gear, t, fixed on the upper end of the'shaft o, engages with a bev-elled pinion, u, fixed on the. cranked shaft, this latter shaft having, while the loom is in operation, a constant rotary motion, will impart such a. movement to the inclined shaft, whose crank, while revolving, will so move the link las to cause it to alternately pullv on the straps e c, and produce reciprocating longitudinal movements of the lay-rack.

The above described invention is the subject of a patent numbered 54,742, and granted to meon 15th day t of May, A. D. 1860, such invention being a new `or improved mechanism for operating the lay rack for com-` municating motion to the various shuttles of a tape lom.

Instead of forming the lin'k l of such mechanism with a cylindrical holet receive the wrist m of the crank n, I now form such link with au elongated slot or groove, v, going through it, and being to receive the wrist m.

This elongated hole allows or causes the lay rack. to remain-at rest a short period of time before each longitudinal movement of it takes place. This stoppage ot' the lay-rack .for a while' at each of the extremes of itsf movement, is found to be essential and of advantage in the weaving of certain kinds of tapes or goods. The tapes, passing down from the breast beam E, are led around a series of` rollers, F F F', and between them and a series of pressure rollers, G G G. Each of such pressure rollers' isi'supportcd bymeans of a hanger, H, arranged at an acute angle with the lower surface of the breast beam, that is, in manner 4and with rsepect to the take-up roller, with which such roller, G, operates, as represented in iig. 3. The hanger H is to be hinged.` to the breast beam in'order that the roller of such hanger may bemoved up and down in a circular arc, whose t centre is at the junction of 'the hanger and the breast beam. This application of each top or pressure roller to` the loom, vin: by an inclined hanger, isof` great advantage, as itenables the roller to be readily moved oii` and above its fellow roller, the same-being accomplished simply by pressing the top roller forward. In constructing thc series of' take-up rollers, I form each set of them of a series of annuli, :c :v z, and two short cylinders, yy,

arranged at equal distances apart, and connected by a series of parallel bars or connectors, w w w w, disposed at eqmldismnces apart, and in manner' as shown in figs. 2 and 3, and also in .gs. 5 and 6, one -of which is a longitudinal section of the two sets or series of take-up rollers, the other being a transverse section of one of i such sets. Each of such series of rollers I form with one long journal, z. The inner one of the series I make,

with :mother journni, a, to reet on :L central bearing, b; The journe a also has o round heeii, @Geest on it, and such journal projects beyond this hood, ond into n corresponding socket, d", matie :axially in the rst roller of the next series-o' Loka-up rolers. A stud, f', projecting from ine side of the said innen roiiei, enters e. eori'esponding hoie made in the head c. By .thueoonnecting the two series of roliers they wiiil operate t0 'better advantage than when conjoined eepnmbeiy, in onse of weer ofthe central journal and its bearings.

Whnt'l'clam as of my invention is as follow-s.: A 'cinim the combination of the slot v, or its eqnivalent, with -the mechanism, substantially for operating bhelnynnok, es sot forth, such mechanism v consisting not only of the link Z, the straps e e, and their guide- Wheels as np'pied to the ley and its mok, substnntiolijf-ee described; 'ont of the crnnk n, the shaft o, and the nevei gea-rs t u, or their meohnniczii equivalent or equivalents, operated by the cranked shaft of the iey.

I also claim the above described modo of making ea-ch of the series of take-up roliers', viz: of two heads, e series of annuli and crossbow, oroonneotors, as set forth. I]

I else claim the application of each of the top or pressure roiiers to theloom, viz: oy means of en inclined honger, to operate Substontioily ns fiescribed.

also claim the appoaton of one series of take-up rolleysio the other seriesvk thereof,'substontini1yin manner es deseribed,ti1atis, by means of the heed'c, the journal a, socket lll/,amd stud f, erienged and applied to the two series ne set'forth. I
